Knowledge about lifting tools

The knowledge of lifting tools, including concepts, uses, classification, performance parameters, working characteristics, and use, etc., is an introductory knowledge to understand lifting tools, and it must be understood. If you do not understand, then you ca n’t talk about using it. So, it is necessary for the editor to introduce this knowledge, and it also shows that the content of this article is very applicable and not to be missed!
1. Concept
Lifting tool is a kind of handling tool, and it is also a tool that works intermittently and can lift heavy objects. It can complete the handling of materials by lifting or lifting. One of its working cycles includes retrieving, moving and unloading, and the corresponding agencies work intermittently. Specifically, after the spreader is reclaimed, it starts to move vertically or vertically and horizontally. After reaching the destination, the spreader is unloaded. After the unloading is completed, the trip is empty to the reclaiming location, and then the second lift is carried out.
2. Use
It is mainly used to transport finished items. If equipped with grab buckets, it can transport bulk materials such as coal, ore, grain, etc .; if equipped with buckets, it can lift liquid materials such as molten steel. In addition, some lifting tools can also be used to carry people.
3. Classification
According to different structures, lifting tools can be divided into light and small lifting equipment, hoists and overhead monorail systems.

4. Performance parameters
Lifting weight: refers to the maximum weight allowed to lift heavy objects under the specified working conditions, and can also be called the rated lifting weight.
Working level: It is a performance parameter that reflects the overall working condition of the lifting tool, and it is also an important basis for its design and selection. It is determined by the total number of work cycles and load status that the lifting tool needs to complete during the required period of use.
5. Working characteristics
(1) Small size and simple structure, can complete lifting and horizontal movement.
(2) The weights lifted by the lifting tools are varied, so the load is variable and the shape is very irregular.
(3) Some lifting tools need to be operated in a larger space, and some need to be equipped with other devices, but generally speaking, the activity space is relatively large, and once an accident occurs, the consequences are not small.
(4) There are many exposed and moving parts of the lifting tools, and they are often in direct contact with the lifting operators, so there are some potential risk factors.
(5) The working environment of lifting tools is complex, and some dangerous factors are often encountered in the working place, so it will pose a threat to equipment and operators.
(6) During the operation, multiple people are often required to cooperate and work together. Therefore, the close cooperation between multiple operators must be coordinated with each other, and the operators must be capable of handling emergency situations on the spot.
6. Use
Lifting tools can be used alone or as an accessory, depending on the needs.
